    This is the story of mandala air flight 091. On the 5th of september 2005 a boeing 737-200 was to fly from polonia international medan to soekarno international airport. This would be the second flight of the day for the crew. They had flown the plane in from soekarno hatta international airport. With all the paper work in order, the crew started the engines and pushed back from the gate and made their way towards runway 23 via taxiway alpha. Within minutes they were at he runway and the controllers were telling the controller was telling the crew what to do after they took off and it was the standard stuff, they had to fly the runway heading then turn left to 120 degrees then maintain 1500 feet. And then the 737 was ready to go down the runway. As the plane picked up speed onlookers noticed that this takeoff was not like other ones. The plane was starting to run out of runway and the nose hadnt even lifted off yet. Something was very wrong with this takeoff and the people who were watching on in horror knew that. The tail of the plane was now scraping aling the runway. The plane then lifted off but it wasnt out of the woods yet. It looked unstable the the plane was rolling from side to side. Flight 091 was fighting to stay airborne. But it was a losing battle. The left wing of the plane then crashed into a building and then the jet with 117 people onboard burst into flames. Only 17 people made it out alive. The tail of the plane had separated and the rest of the plane was in shambles and a fire had broken out, the crash site was something out of a post apocalyptic movie. The buildings were on fire, the plane was broken up into many pieces and there were fruits strewn all around the place. The plane had unfortunately taken the lives of 49 people on the ground and injured a further 26 more. So how did a jetliner just fail to take off? It's not like you just line up with the runway and gun it and pray that the plane takes off, pilots do a lot of meticulous calculations to make sure that the plane has enough velocity and runway to get airborne safely. But as soon as the crash had happened, local media was rife with theories on how this plane crashed. One of the main theories was that the engine had a failure and that's why the plane crashed. This theory had come out just days after the crash, but was this true? The investigators found the engines and then took them to the hangar to get them checked up, to see if they had failed on takeoff. The engines were broken, the lighter parts of the engines were destroyed, obliterated if you will but the investigators were interested in the blades of the engine. They looked at the tips of the blades and lo and behold the tips were broken, this was a characteristic of the blades being at a high RPM, when they looked at the second stage blades they saw the same thing all over again.the damage inside the engine was also consistent with damage that you would expect to see when the engine broke up when it was operating at a high power setting, so despite what the media was saying this plane did not crash due to an engine failure these enignes were at max power when the plane crashed and they were doing everything that they could to get this plane into the air before the runway ran out. The engines also did not show any signs of overheating. When the investigators got their hands on the CVR they were in for a shock, the CVR was basically useless in this case. The cockpit area microphone did not record much of the sounds from the cockpit. There was a hum that drowned out most of the noise from the cockpit. The noise that was recorded on the CVR lead the investigators to believe that the wiring in the CVR was faulty. But this meant that the investigators had no idea what was happening in the cockpit. The sound distortion was so bad that the investigators couldnt even hear the sound of the stickshakers going off in the cockpit and those usually are pretty loud and if anything was going to be picked up by the faulty cockpit area microphone that would be it. With the CVR of no use the investigators had to solve this crash with one arm tied behind their back. They then tested, the fuel at the airport to see if they had been contaminated in some way bad fuel can rob the plane of power sometimes. The tests came back negative, nothing was wrong wit

    In 1987, Northwest Airlines 255, an MD-82, took off from Detroit and quickly crashed, with the same problem of the pilots not extending the flaps. 156 people were killed. This was highly publicized, and for a while more than a few passengers (including me) looked nervously so see if their planes' flaps were set. On one flight I was on the pilot announced: "And for you flap watchers, we have set the flaps to [xxx]."

      As flap set is soo crucial, my suspicion is that along with the hum on the cdr, there may have been pilot headsets issues as well, orrrr, the hum was very loud within the cockpit, which would be a major distraction to both pilots, and we all know what may happen when any vehicle driver loses situational awareness?

      I had the exact opposite error during my first solo. Atc rushed me and as a result I never reconfigured the c152 for departure. I took off with full flaps and carburetor heat engaged. At around 100ft I realized why it was climbing so poorly and promptly retracted All flaps. As I was sinking rapidly I noticed the carb heat, and that finally gave me the performance to stop the sinking until sufficient airspeed built.

    I still clearly recall that accident, because I was living near that airport at the time. This accident is the one of main reasons that Kualanamu International Airport is being built, and the older Polonia airport transformed to Soewondo Air Force Base (planned to move at Langkat Regency after another fatal accident involving C-130 in 2015). Local media also told us if this accident is caused by the smell of 2 tonnes durians that our North Sumatra Governor and ex Governor brings to Jakarta for routine meetup with others Governors and Mr. President. And finally, KNKT (our local safety committee) publishes that this resulted in a pilot error.

    My father was in a TransBrasil flight once where they began the takeoff roll without flaps or slats and my father thought "wow, we're gonna takeoff without flaps. This plane must be very light". But no, a few seconds later they aborted the takeoff and even blew a tire while braking.

    Spanair Flight 5022, Madrid 2008, featured on Air Crash Investigation. They took off without flaps because on the taxy out they had a minor tech issue so taxied back to the hangar. The captain asked for a clean up, including flaps up. The groundcrew pulled a CB for an unrelated system, but it actually disabled the flap warning system. On taxy out the captain asked to FO to continue the takeoff checks from earlier..... Which he did.... Except he was already past flaps/slats, so they never got deployed. The warning system was disabled and they took off clean. A lot of people were killed in that one.

    Stuff like this happening was more commonplace in the past, especially for airlines based in countries that had less-strict rules and regulations about aviation safety culture. It is a horrible tragedy, but nowadays commercial aircraft across the globe are so advanced that it's pretty much near impossible to accidentally improperly configure them for takeoff, because of crashes like this there are now far more robust training systems for pilots and more apparent built in warnings for improper aircraft configuration. RIP to all who perished in this crash.

    Because they have VIP onboard . The pilot and co pilot might have been distracted .
    They were busy greeting and talking to the VIP which were the current Governor and the previous governor of North Sumatra province .
    The distractions of the VIPs onboard might cut into their preflight check.
    We would never know due to the cockpit voice recorder .
    Too bad .
    Until today the perception of 2 tons durian caused the crash is still very ripe and strong among the people in Medan.
    But all the Flap and slat were recovered and confirmed to be in retracted position

    I remember reading an accident report for an incident where a single engine plane lost engine power during flight as a kid (one of my parents had a private license so I got to read the quarterly safety newsletter when they were done with it. They said it was the longest period of peace and quiet they ever got with me). It was referencing an incident where the spark cables hadn't been tightened down after maintenance. The conclusion was that the mechanic had been interrupted during the maintenance and forgotten to tighten down the spark cables. The reason given for this was that humans generally think three to five steps ahead of the current step. So if a person is interrupted during a checklist, there s a good chance that they will restart the list three to five steps beyond the step they had been working on unless they have a notation to show where they stopped.

    Durian fruits are not small, they’re as big as your head! And they really smell awful, kind of like a combination of overripe bananas, an oil refinery, and sweaty gym shoes. But they’re considered delicious in some parts of the world. However, even in those areas there are places you aren’t allowed to take them (like in trains, hotels etc) because of the smell which spreads everywhere. I’ve tried eating durian a few times, it looks and tastes kind of like a strange soft stinky cheese.

      This is an experience of a couple of months ago. I noticed that the slats and flaps weren’t extended as the plane was taxiing to the edge of the runway and I brought it to the attention of the steward. She kind of said that the cockpit crew knows all and when I insisted that she speak to the Captain, she checked with a FO who was sitting 3 rows behind me, who assured us that the plane was configured right. I was unconvinced and thankfully as the plane was some 100 m from the edge of the runway the flaps and slats were extended. I guess the alarm must have sounded and the captain corrected the configuration. Till date I can’t believe the FO or whosever it was sitting behind me actually thought it was all fine

  • @b.t.356

    Initially, I was convinced that it was miscalculated weight at first, knowing that miscalculated weight has caused aircraft tails to drag on the runway. I was surprised that it was a misconfiguration, since the videos I've seen on flights such as Northwest Airlines Flight 255, Spanair Flight 5022, and Lufthansa Flight 540 showed the planes taking off normally before disaster struck rather than the tail dragging on the ground due to the crew neglecting to properly set slats and flaps.

    I was flying a Northwest 757 that afternoon that took off 3 planes ahead of Flt. 255. There were thunderstorms in all quadrants as the afternoon mass of flights pushed and got in line for departure. Then they changed the departure runway and 40-50 flights from DC-9's to 747's had to resequence to the other end. So we were trying to figure out how this was going to work while avoiding everyone, checking the weather on our departure path and doing our checklists. In my 27 years with NWA it was probably right up there in the 2 or 3 most stressful departures. This is not to excuse 255, checklists are there for a reason, but it's not unthinkable.

    I don't love the outcomes in these ones - even though it's already happened, the tale is so well told here that it always feels like reliving it - where, on other occasions that it is not apparent whether the flight makes it in one piece back on to the ground until much later, I always breathe a sigh of relief when the pilots manfully wrestle the beast into submission irrespective of the sex of the one at the controls!! It's like witnessing the whole heart-in-mouth drama in person. Unfortunately, unlike with the flight which I recall took off from Athens which literally took the ariels off the top of buildings, but survived, this one was less fortunate..
    The fact the engines had been found to be working, I straight away thought "overweight" - or "forgot flaps" although "dodgy fuel" hadn't occurred to me - just goes to show that no matter how many episodes I watch, there's always something more to learn and consider. I do now remember hearing about microbes in fuel on this channel - and how a mix up with metric and imperial measurements when putting the anti-bac in the jet fuel caused an issue....haven't gone totally senile just yet!!

    @georgeconway4360 Год назад

    Some airplanes can take takeoff with no flaps. Normally it is done when the temperature and the airport elevation are high and there is enough runway to permit. I know the DC9 does it at times. I never flew the -9 but I recall a friend talking about zero flap over speed takeoffs out of Nairobi which is at around 5400’ elevation with a long 13,000’ runway. I flew both the MD11 and MD10. The MD11 never used zero flaps but the MD10 did. It was the MD10-10 was the one that normally did the zero flaps because the airplane could not make the second segment climb requirements at higher weights. A very long runway was required. Then about a year before I retired some genius decided to make All MD10 takeoffs minimum flaps which was zero on the MD10 in order to save fuel. The result was a zero stop margin in the event of an engine failure at V1. That procedure was quickly revised to a minimum flap of 5 degrees. There is no such thing as a no slat takeoff. If you see a wing with no slats the crew has forgotten the flaps/slats and I would start screaming if a takeoff was started. If you see no flaps or slats during taxi it my be normal. When we didn’t start all engines to save fuel on taxi we did not extend flaps until all engines were started.

    I think they probably did extend the flaps but when it became obvious they werent lifting off maybe they put them back down in the hopes of stopping the plane before it hit something. I dont see how it would be possible for them to ignore the warning even if they missed checking it.

    British European Airways Flight 548, Delta Air Lines Flight 1141, LAPA Flight 3142, Lufthansa Flight 540, Northwest Airlines Flight 255, Spanair Flight 5022, all crashed because of retracted flaps/slats. All in all some 500 people died because of pilots negligently skipping this basic step. My heart goes out to the victims and their loved ones.

    As the video states, the flaps are a very basic part of take off. I believe that’s why these things happen. The pilots basically have it in their heads “Well of course the flaps are extended.”

    look at the Royal Air Maroc flapless take off at Frankfurt on RUclips. The airline reps later heard a "caution vortex" on the ATC tapes, and immediately tried to blame that. In reality that was for traffic a on a cross runway a mile behind where the 737 almost crashed on departure. The flaps were clearly not set.

  • @PassiveSmoking
    @PassiveSmoking Год назад +1

    It's ever more common for modern planes to have computerised checklists, how much additional work would it take for the system to physically forbid takeoff until the proper pre-takeoff checklists have been completed (for example by ignoring all throttle input greater than that needed for taxiing until the flaps/slats are configured)?

Not relevant to the video, but it made me chuckle a little because that fruit is deceptively heavy,

  • @orazha
    @orazha Год назад

    I'd watched a video that, I believe, involved the flaps on take-off. I'm not a pilot, just watch a lot of these videos. If I'm remembering right, the plane had some maintenance done in which the control for the flaps had to be removed. When the controls were replaced, the maintenance person mistakenly put them back in upside down. So the pilots thought they were extending but were actually retracting. I believe that the video suggested that this led to the redesign of the controls so that this couldn't happen again.
    I thought this was going to be a different video about the same event.

    As soon as I saw the aircraft from 00:51 onward it was obvious that leading edge slats were not deployed. Then by 1:01 it's obvious that the triple slotted trailing edge flaps that the old 737's had were similarly undeployed. God Bless those who passed away... my next question, without watching further yet than 1:01 is did the 737-200 have a take-off mis-configure warning horn at this time?

  • @Cassandra17311

    7:35 "[Setting the flaps for takeoff] is one of the first things they teach you in flight school."
    Most pilots learn to fly in small airplanes, and for most small airplanes the recommended take off procedure is to use flaps only when taking off from short or grass runways. So, that's not actually true :-)

  • @theresacaron4238
    @theresacaron4238 Год назад +3

    One of the first item on the checklist after engine start is extension of flaps and slats. The degrees of flap extension are calculated to deal with the weight of the aircraft, runway length, weather conditions, etc. In addition, flight recorders on older aircraft were the foil type and did not record many parameters as compared to the current digital recorders. I think the pilots did not follow their checklist for whatever reason and killed their passengers and innocent people on the ground.

    Having a browse around the cockpit panel and the centre console where the thrust flaps and spoilers are could save them. What were they looking at? It would stand out clearly.
